We're really loving this new campaign!
In order to prove just how bubbly she really is, the Pitch Perfect 2 star does whatever she can think of to impress the director, including taking a bubble bath and donning Lady Gaga's infamous bubble dress.
We have to hand it to Brittany, she really has such great delivery and comedic timing.
She's just so adorably funny!
Ch-ch-check out her master plan to be the new Lipton spokesperson (above)!!!
